Gravitational lensing by cosmic strings: what we learn from the CSL-1 case
M. V. Sazhin, O. S. Khovanskaya, M. Capaccioli +5
Cosmic strings were postulated by Kibble in 1976 and, from a theoretical point of view, their existence finds support in modern superstring theories, both in compactification model…
New optical and near-infrared Surface Brightness Fluctuations models. A primary distance indicator ranging from Globular Clusters to distant galaxies?
M. Cantiello, G. Raimondo, E. Brocato +1
We present new theoretical models for Surface Brightness Fluctuations (SBF) both for optical and near-infrared bands in standard ground-based and Hubble Space Telescope filter syst…
ROSAT-HRI investigation of the NGC 507 X-ray halo
M. Paolillo, G. Fabbiano, G. Peres +1
We present an X-ray investigation of the elliptical galaxy NGC 507. We make use of archival Rosat HRI, PSPC and Chandra data, to connect the large-scale structure of the halo to th…
GOHSS: a Fibre-fed Multiobject NIR Spectrograph for the Italian Galileo Telescope
R. Scaramella, E. Cascone, F. Cortecchia +6
We present the concept and preliminary design of the Galileo OH Subtracted Spectrograph [GOHSS], a multifibre NIR spectrograph for faint objects. The instrument represents a collab…
